4-Way Mono Operation

Set the PCX4000 to 4-way mono by using the Mode buttons on
the rear of the device (the left button should be released, the right
button pushed-in). When set correctly, the mono LED on the front
of the device will light up, as well as the corresponding function
buttons. When set to mono, the various controls on channels 1
and 2 will work as the single mono channel's controls.

1. Input Control
This control will adjust the input gain between -12 and +12 dB.
2. Low Cut Button
Pushing this button will activate a low cut (high pass) filter, set
at 25 Hz, which will help protect woofers from extremely low
frequency signals.
3. Low/Low-Mid Crossover Frequency Control
This control will determine the crossover frequency between
the low and low-mid frequency signals. When the Crossover
Frequency button on the rear of the device is pushed in, the
frequency range is multiplied by a factor of 10.
4. Low-Mid/High-Mid Crossover Frequency Control
This control will determine the crossover frequency between the
low-mid and mid-high frequency signals. When the Crossover
Frequency button on the rear of the device is pushed in, the
frequency range is multiplied by a factor of 10.
5. Delay Control
Use this control to add a delay of up to 2ms to the low frequency
output. This allows users to better align speakers in phase.
6. Low Output Control
This controls the level of the low-band output between -6 and
+6 dB.
7. Low Phase Invert Control
This button reverses the phasing of the low-band output, making
the signal appropriate for out-of-phase or incorrectly wired
speakers.
8. Low Mute Button
Pushing this button will mute the low-band signal.
9. Low-Mid Output Control
This controls the level of the low-mid-band output between -6
and +6 dB.

10. Low-Mid Phase Invert Button
This button reverses the phasing of the low-mid-band output,
making the signal appropriate for out-of-phase or incorrectly
wired speakers.
11. Low-Mid Mute Button
Pushing this button will mute the low-mid-band signal.
12. CD Horn Button
Pushing this button in will provide frequency correction on the low-
band output ideal for use with constantdirectivity horns.
13. High-Mid/High Crossover Frequency Control
This control will determine the crossover frequency between
the high-mid and high frequency signals. When the Crossover
Frequency button on the rear of the device is pushed in, the
frequency range is multiplied by a factor of 10.
14. High-Mid Output Control
This controls the level of the high-mid-band output between -6
and +6 dB.
15. High-Mid Phase Invert Button
This button reverses the phasing of the high-mid-band output,
making the signal appropriate for out-of-phase or incorrectly
wired speakers.
16. Mid-High Mute Button
Pushing this button will mute the mid-high-band signal.
17. High Output Control
This controls the level of the high-band output between -6 and
+6 dB.
18. High Phase Invert Button
This button reverses the phasing of the high-band output, making
the signal appropriate for out-of-phase or incorrectly wired
speakers.
19. High Mute Button
Pushing this button will mute the high-band signal.
20. Threshold Control
This control determines the threshold of the built-in limiters. Users
can adjust the threshold between -8 dB and OFF.
21. Limiter Button
Pushing this button activates the built-in limiter circuits. When the
signal on any of the outputs surpasses the set threshold, the limiter
is engaged and the corresponding 'LIM' LED (located above the
output's controls) will light up.
